Subject: [PATCH v1 0/3] perf more ELF machine usage

Switch 3 more cases where the perf_env arch was being used to
determine the architecture type and switch to using the ELF
machine. This includes the addition of minimal instruction parsing in
perf script for architectures other than x86, or x86 when
cross-platform.

Note: this series will conflict with the e_flags series:
https://lore.kernel.org/lkml/20260123222209.1181249-1-irogers@google.com/
that adds an additional out argument to thread__e_machine. In all the
cases here that argument should be NULL. So:
  thread__e_machine(thread, machine)
becomes:
  thread__e_machine(thread, machine, /*e_flags=*/NULL)

Ian Rogers (3):
  perf script: Fix script_fetch_insn for more than just x86
  perf callchain: Switch callchain_param_setup from an arch to an
    e_machine
  perf thread-stack: Switch thread_stack__init to use e_machine
